使用getter setter从firebase获得所有价值

Question

我很难如上所述获得数据库中的所有值。如果使用getter设置器，则问题已解决，但我无法在名称为day和timestamp的子节点的登录/上获取数据。

        public String email;
        public String gaji;
        public String id;
        public String jasapelayanan;
        public String nama;
        public String pass;
        public String status;
        public String idcase;

        public getFIngerprintAllDataChildren(){

        }



    public getFIngerprintAllDataChildren(String alamat,
    String idcase,
    String email,
    String gaji, 
    String id, 
    String jasapelayanan, 
    String nama,

        this.id = id;
        this.jasapelayanan = jasapelayanan;
        this.nama = nama;
        this.pass = pass;
        this.status = status;
        this.terpakai = terpakai;
        this.jabatan = jabatan;
        this.nip = nip;
        this.tl = tl;
        this.idcase = idcase;
        this.alamat = alamat;
        this.signin = signin;
        this.signout = signout;

    }

    public Object getSignin() {
        return signin;
    }

    public Object getSignout() {
        return signout;
    }

    public String getAlamat() {
        return alamat;
    }




    public String getIdcase() {
        return idcase;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getGaji() {
        return gaji;
    }

    public void setGaji(String gaji) {
        this.gaji = gaji;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getJasapelayanan() {
        return jasapelayanan;
    }

    public void setJasapelayanan(String jasapelayanan) {
        this.jasapelayanan = jasapelayanan;
    }

    public String getNama() {
        return nama;
    }

    public void setNama(String nama) {
        this.nama = nama;
    }

    public String getPass() {
        return pass;
    }

    public void setPass(String pass) {
        this.pass = pass;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getTerpakai() {
        return terpakai;
    }

    public void setTerpakai(String terpakai) {
        this.terpakai = terpakai;

    public String getJabatan() {
        return jabatan;
    }

    public void setJabatan(String jabatan) {
        this.jabatan = jabatan;
    }

    public String getNip() {
        return nip;
    }

    public void setNip(String nip) {
        this.nip = nip;
    }

    public String getTl() {
        return tl;
    }

    public void setTl(String tl) {
        this.tl = tl;
    }

这是我的DatabaseReferenceListener，它在上面使用了构造方法

          myRef.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {

                int i =0;
                List<getFIrebaseTimeStamp> sign = new ArrayList<>();
                for( DataSnapshot ds : dataSnapshot.getChildren()){


                    getFIngerprintAllDataChildren getFIngerprintAllDataChildren 
                    = ds.getValue(getFIngerprintAllDataChildren.class);
                    list.add(getFIngerprintAllDataChildren);
                }
     }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {


            }

        });
